wnnrrmdn-Aonmn To all whom it may concern: a

Be it known that I, WILLIAME. IVIILIL R, a citizen of'the United States, residing at Gobleville, county. of Van Burem State of Michigan, have invented certain new and useful Improvements in Wrapping-Ma chines, of which the following is a specification.

This invention relates wrapping machines.

My improved wrapping machine is especially designed 'by me for the wrapping of wax pa er upon loaves of bread and the.

like, alt ough desirable for use in other relations. i

The main objexzts of this invention are First, to provide an improved wrapping machine which 1 simple and convenlent to Second, toprovide an improved wrapping machine which is slmple and economical and compact in structure.

from the detailed description to follow.

I accomplish the. objects of my invention by the devices and meansdescribedin the following specification.

in the accompanyingv drawing, forming a part of this specification, in which: Figure I is a plan view of a structure embodying the features of my invention, the} operative relation to a.

sealing machine.

to improvements in v p taken looking in the direction of the little The invention is clearly'defined and pointed out in the claims':

A structure which is a preferred embodiment of my invention is clearly illustrated 'tudinal section on a line corresponding to ine 5-5 Patented Dec. 9, 1919..

lines and lines. p H VIII is an enlarged detail vertical section on a linecorresponding to line 8'8 of Figs. I and III, showing details of the a In the drawing slmilar reference characters refer to. similar parts throughout the :in another position by dotted several views and thesectional lines are arrows at the ends of the section lines.

' Referring to thedrawing, 1. represents a.

sealing machine; As the details of this ma; chine form no part of my present'invention they are-not illustrated or described herein.

My improved Wrapping machine comprises a pair of bed members 2 and3, the bed member 3 being secured upon the standards 4 by means of the bolts 5. 'The bed memher '2 rests upon thestandards 4 and is slid ably mounted upon the rod 6 projecting pfrom the-bed member 3. Further" objects, and objects relating to structural details, will definitely appear other articlesv of difi'erent size. Onthese bed members 2 and 3 are way bars 8' formmg a way upon which the loaf to .'be wrapped is pushed: through the machine. The forwardly inclined late 9 constitutes the front of the way. T is plate is secured to one way bar as at 10, the other side overlapping but being unconnected with. the

other way bar, so that it does not interfere with the adjusting o f the machine. 11 indicates the loaffto be wrapped and 12 its wrapper. Y

For convenience in description I refer to I first partially wrapped around the article, the ends or; flap fold portions being unfolded. As' thearticle' ispushed along the way it engages the trip 17 of the catch .18 which coacts with the keeper 19 on the rock shaft 20 to retain the. rock shaft in its inias rear, front, bottom and top flaps, 13 indicating the rear flap, 14 the front flap, v15 the bottom fiapand l6-the'top flap,-see

he article tobe wrappedis pushed along i I the way by hand, the wrapper having been p tialpositiom This rock shaft is disposed transversely below the; way and carries the flap folders 21 which swing forwardly when,

the trip is Ireleased to fold therear flaps 13 forwardly upon the article, the rock shaft front flaps are folded rearwardly upon the folded rear flaps by means of the blade-like front flap folders 25 which are mounted onposts 26 disposed at each side of the way so that the flap folders project inwardly and forwardly as shown in Fig. l. Springs 2? urge these'flap folders 25' inwardly. As the article is pushed along its bottom flap 15 is engaged by the rearwardly inclinedflap folders 28 which are disposed to project upwardly at the sides of the way. lhe upper edges of theseflap foldersiare preferably turned outwardly at 29. The top flaps 16 are turned downwardly upon the bottom flap by means of the top flap folders 30 which are forwardly inclined and disposed at the sides of the way to overhang the bottom flap folders 28, the top and bottom flap folders being so arranged that the bottom flaps are turned or folded prior to the completion of the folding of-the top flaps.

After leaving the flap folders the 7 flaps are retained in their folded relation or held against the ends of the article by the plates 31 until they are engaged by the side plates 32 of the sealing machine.

My improved sealing machine isvery simple and economical in structure and at the same time enables the rapid and satisfactory wrapping of articles such as loaves of bread.

those skilled in the art to which my invenl have illustrated and described my improvements as l have embodied and adapted the same forwrapping loaves of bread. l have not attempted to illustrate or describe other modifications'or adaptations as l 'helieve. the disclosure made will enable tion relates to embody or adapt" the same as may he desired. I

Having thus described my invention, what I claim asnew and desire to secure by Letters Patent, is: I

1. In a wrapping machine, the combination of a way, a rock shaft disposed trans-l versely below the way, an actuating spring for said roclrshaft, a catch for retaining e saidrock shaft in its initial position provided with a trip progecting into the path of an article pushed along the way, a pair of rear flap folders on said roclr shaft which swings forwardly when said trip is released and folds the rear flaps forwardly, a return le erefor said rocl: shaft, posts dis- 1 posed at'thes ides of the way, yielding forwardly inwardly projecting front flap folders mounted on said posts and provided folded rearwardly as the article is pushed resales rearwardly inclined bo tom flap folders disposed at the sides of the way engaging the bottom flaps and folding them upwardly as the article is pushed along the way, and a pair. of forwardly inclined top flap folders disposed at the sides of theway overhanging said bottom flap folders engaging the top flaps and folding them downwardly as the article is pushed along the way.

2. In a wrapping machine, the combination of a Way, a rock shaft disposed trans. versely below the way, anactuating spring for said rock shaft, a catch for retainiiig said rock shaft in its initial position proyided with a trip projecting into the path of an article pushed along the way, a pair of rear flap folders on said rock shaft which swings forwardly when said trip is released and folds the rear flaps forwardly, a return lever for said rocl: shaft, yielding front flap folders mounted so that the front flapsare along the way, a pair of rearwardly inclined bottom i'iap folders disposed at the sides of the way engaging the bottom flaps and folding them upwardly as the article is pushed along the way, and a pair of forwardly inclined top flap folders disposed at the sides of the way overhanging said'bottom flap folders engaging the top flaps and-folding them downwardly as the article is pushed along the way.
